$150 is $130 more than $20. It depends on if an ISA type computer

know what you mean about maintenance so i don't want any disk inside
and no OS installed.
I'm surprised that no one has built a GPIB controller from a uP.
Electrically the GPIB is simple and slow by modern standards.
That's exactly what the Prologix is... a microcontroller that implements
IEEE-488/GPIB with a command interface (serial port emulation with USB)
Maybe what you mean is "why has nobody published a design and software
for free?"
